pub async fn new<P: AsRef<Path>>( token: CancellationToken, output_path: P, max_lines_per_file: Option<usize>, max_count: Option<usize>, max_time: Option<f64>, ) -> Result<Self>
Create a new Recorder that streams events directly to a JSONL file
§Arguments
token- A cancellation token for managing shutdownoutput_path- Path to the JSONL file to write events tomax_lines_per_file- Maximum number of lines per file before rotating to a new file. If None, no rotation will occur.max_count- Maximum number of events to record before shutting down. If None, no limit will be applied.max_time- Maximum duration in seconds to record before shutting down. If None, no time limit will be applied.
§Returns
A Result with a new Recorder that streams events to the specified file
Sourcepub fn event_sender(&self) -> Sender<T>
pub fn event_sender(&self) -> Sender<T>
Get a sender that can be used to send events to the recorder
Sourcepub async fn event_count(&self) -> usize
pub async fn event_count(&self) -> usize
Get the count of recorded events
Sourcepub async fn elapsed_time(&self) -> Result<Duration>
pub async fn elapsed_time(&self) -> Result<Duration>
Get the elapsed time since the first event was received
Returns a Result with the elapsed time or an error if no events have been received yet
Sourcepub async fn send_events<P: AsRef<Path>>(
filename: P,
event_tx: &Sender<T>,

) -> Result<usize>
pub async fn send_events<P: AsRef<Path>>( filename: P, event_tx: &Sender<T>, timed: bool, max_count: Option<usize>, max_time: Option<f64>, ) -> Result<usize>
Send events from a JSONL file to the provided event sender
§Arguments
filename- Path to the JSONL file to read events fromevent_tx- A sender for eventstimed- If true, events will be sent according to their recorded timestamps. If false, events will be sent as fast as possible without delay.max_count- Maximum number of events to send before stopping. If None, all events will be sent.max_time- Maximum duration in seconds to send events before stopping. If None, no time limit.
§Returns
A Result indicating success or failure with the number of events sent

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
